read_iacr_paper

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

No annotations are provided, so the description carries full burden. It mentions the tool reads and extracts text, implying it downloads or accesses a PDF, but doesn't disclose behavioral traits like network usage, error handling, file system operations (saving to 'save_path'), or performance characteristics. The description adds minimal context beyond the basic action.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is well-structured and appropriately sized: a clear purpose statement followed by Args and Returns sections. Each sentence earns its place by defining the tool, parameters, and output. It could be slightly more concise by integrating the default into the purpose, but overall it's efficient.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given the tool's moderate complexity (2 parameters, no annotations, but with an output schema), the description is reasonably complete. It covers the purpose, parameters, and return value. The output schema exists, so the description doesn't need to explain return values further. However, it lacks details on prerequisites or error conditions, leaving some gaps.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 0%, so the description must compensate. It adds meaning for both parameters: 'paper_id' is explained as 'IACR paper ID' with an example, and 'save_path' specifies the directory purpose and default value. This provides clear semantics beyond the bare schema, though it doesn't detail format constraints or edge cases.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the tool's purpose: 'Read and extract text content from an IACR ePrint paper PDF.' It specifies the verb ('read and extract'), resource ('IACR ePrint paper PDF'), and output ('text content'). However, it doesn't explicitly differentiate from sibling tools like 'download_iacr' or 'read_arxiv_paper' beyond the IACR focus.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description provides no guidance on when to use this tool versus alternatives. With many sibling tools for different sources (e.g., 'read_arxiv_paper', 'download_iacr'), it doesn't explain if this tool downloads first or requires a pre-downloaded PDF, or when to choose it over other IACR-related tools.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
